WOVEN PILE FABRIC.

Application filed October 28, 1925.

This invention relates to improvements in woven pile fabrics of the'Vilton7 class wherein sets of pile threads are floated in lappingrelation between upper and lower weft strands or threads and extendedupwardly at certain intervals between adjacent upper weft strands toforni the pile of the fabric, the pile threads being confined betweenthe upper and lower weft strands, and the weft strands being bound intothe fabric by binding warp threads.

The invention aims to cheapen the cost of production of fabrics of thisclass and to provide a novel fabric structure which can be produced inless time than heretofore and which will be. strong and durable when inservice.

rThe desired aiin is accomplished by interweaving a continuous threadforming the weft strands with the pile threads and binding warp threadsin a novel manner, as will be hereinafter explained; and the inventionconsists of the elements and the co1nbina tions of them hereinafterdescribed and particularly claimed.

In the accompanying drawings illustrating the invention:

Figure l is a side view of a pile fabric embodying my invention, as seenfrom one of the lateral edge portions thereof.

Figure 2 is ay side view of the fabric as seen from the opposite lateraledge portion thereof.

Figure 3 is a long-itudinal section through the fabric, on line 3 3 ofFig. 1.

Figure 4'is a transverse section through the fabric, on line 4 4 of Fig.3.

Referring to the drawings, 2 designates pairs of .binding warp threads,5 sets of pile threads, and 6 a continuous thread which forms upper andlower pairs of weft strands 7 and 8, respectively.

The pairs of binding warp threads 2 are arranged atv spaced intervalsthroughout the width of the fabric and the sets of pile threads 5alternate with the pairs of binding warp threads 2 and are arrangedbetween next adjacent pairs thereof, as clearly shown in Fig. 4, andthey extend longitudinally of the fabric or in the general direction ofthe warp threads 2. Any desired or suitable number of pile threads maybe e1nployed in each set 5 thereof, six threads Serial No. 65,298.

being shown in the drawings in each set for convenience of illustration.

The upper and lower pairs of weft strands 7 and 8 extend transversely ofthe fabric from side to side thereof above and below the sets of pilethreads 5, respectively; and the threads of the pairs of binding warpthreads 2 pass above and below the upper and lower pairs of weft strands7 and 8 and cross each other within the body of the fabric, as shown inthe drawings, and thereby bind the pairs of weft strands 7 and 8 intothe fabric and cause them to bind the sets of pile threads 5 into thefabric.

The pile threads of the sets thereof are floated side by sidelongitudinally through the body of the fabric between upper and lowerpairs of weft strands 7 and 8 and between laterally adjacent pairs ofbinding warp threads 2; and, at certain regular intervals throughout thelength of the fabric one thread of each set is extended upwardly betweenadjacent upper pairs of weft strands 7 to form the pile 9 which may becut, as herein illustrated, or which may remain uncut, as desired. Thus,by employing different colors in the pile threads of the several sets 5thereof, different designs may be produced in the fabric, the threads ofthe several sets 5 being floated between the pairs of weft strands 7 and8 when not appearing upon the upper surface of the fabric in the formofthe pile 9.

At the lateral edge portion of the fabric shown in Fig. l. the weftstrands of the upper pairs 7 thereof are connected to the weft strandsof the lower pairs 8 thereof by loop portions lO and l1 which are formedby the continuous thread 6, so that the continuous thread extends aroundthe sets of pile threads 5 in connecting the upper and lower pairs ofweft strands 7 andv 8 at'one lateral edge of the fabric and therebyprevents the pairs of weft strands from being withdrawn from between thebinding warp threads 2 and the pile threads 5 or displacedlongitudinally in the fabric in the direction of the arrow 12 in Fig. 4or toward the edge portion of the fabric shown in Fig. 2. The portions11 of the continuous thread 6 eX tend only around the ioated portionsvof the pile threads 5, and the portions l() alsoexaround the crossedpairs' of binding:

warp threads 2, as shown in Fig. 1, which further prevents suchwithdrawal or longi- `tudinal displacement of the pairs of weft strands7 and 8.

fit the lateral edge portion of the fabric shown in Fig. 2 there isprovided a supple` mental binding thread 13 which extends longitudinally of the fabric or in the general direction of the bindingwarp threads 2 and pile threads 5; and the upper and lower pairs of weftstrands 7 `and 8 Yare connected to this supplemental thread 13 by loops1d; and 15 formed .by the continuous thread 6 and forming extensions ofthe pairs of weft :strands 7 Vand 8 and extending around or embracingthe thread 13, as shown in Figs. 2 ande.' Thus, the supplemental bindingvthread; lprevents the pairs of weft strands 7 andf8 from beingwithdrawn from between thebinding warp threads 2 andthe pile threadsl 5vor displaced longitudinally in the fabricin the direction of the arrow16 in Fig. 4 or toward the edge portion of the fabric shown in Fig. 1.

The course of the continuous thread 6- through the fabric is as follows:From the point- 17 shown 1n Fig. 1, 1t extends above the sets of pilethreads 5 from the edge of the fabric shown in Fig. 1 to the edge showninFig. 2. Itthen forms a loop 14 around the supplemental binding thread13 and eX- tends back above'the'sets of pile threads 5 to the edge ofthe fabric shown in Fig. l. It then'extends around thesets of pilethreads 5 to the bottom thereof andforms a loop 10 from which it extendsbeneath the sets of pile threads 5 to the edge of the fabric shown. inFig.. 2 and there forms a l v 'loop' 15 around the supplemental bindingthread 18, and from this loop 15 it extends back beneath ythe Sets ofpile threads 5 to theedge vof the fabric shown in Fig. 1. It thenextends around the sets ofpile threads 5 and around the crossed adjacentthreads of l15A woven pile fabric comprising pairs Y of binding warpthreads alternating with sets of pile threads extending in the directionof the binding threads, and a continuous thread ypassing under and overthe pile threads and around the same at one lateral edge portion of thefabric and forming pairs of weft strands above and below the pilethreads, a supplemental binding thread eX- tending in the directionofthe warp threads at the lother lateral edge portion of the fabric, eachpairrof upper Vand lower weft strands forming a loop which embracessaidsupplemental,thread, the upper and lower pairs of weft` strandsconfining the sets of pile threads between them and being bound intothefabric by the pairs ofbinding warp threads, and the pile threads `ofeach set thereof extending upwardly between adjacent Yupper pairs ofweft strands at certain intervals and forming pile and 'being floatedside by side in lapping relation between the upper and lower pairs ofweft strands and between laterally adjacent pairs of binding warpthreads when. not forming pile.

A woven pile fabric comprising pairs of binding warp threadsalternating with sets of pile threads extending in the direction of thebinding threads, and a continuous thread passing under and over the pilethreadsand forming pairs of weft strands above and below the same, thecontinuous thread passing around the pile threads at one edge portionofthe fabric vat certain intervals and around pairs of binding warpthreads at the same edgefportion of the fabric at certain intervals` asupplemental binding thread extending in thedirection 'of the warpthreads at the other lateral edge portion of the fabric,eachpair ofupper and lower weft strands forming a, loop which embraces" saidsupplemental thread, the upper and lower pairs of weft strandsconlfiningthe sets of pile threads between Ithem and being bound intothe fabric by the pairs of binding Vi'varp threads. and the pih` threadsof each set thereof extending upwardly between adjacent ,upper pairs ofweft strands at certain intervals and forming pile and being floatedside by side in lapping relation betweenv the upper and lower pairs ofweft strands and between 'laterally adjacent pairs ofrhindng warpthreads when not forming pile.
